Keira Knightley rocks the polar opposite look while promoting the Boston Strangler in New York

Keira Knightley rocked three contrasting looks while promoting her new movie Boston Strangler in New York on Wednesday.

The Pride and Prejudice actress, 37, was the picture of elegance when she stepped out on the Upper West Side.

Keira plays real-life reporter Loretta McLaughlin, who broke the story of a notorious serial killer in the 1960s, in the upcoming biographical drama.

For her first stop on press day, she wore an off-white two-piece with black accents on her belt and leather-studded heels.

She completely reversed the look for her second appearance in a sleek black bodysuit with a white shirt tied with an elegant bow at her neck.

For her look, the actress kept her makeup simple, focusing on her high cheekbones and sharp jawline, while keeping her brunette locks loose and straight off a light wave near the ends.

For the third look, she wore a gray knit cardigan with a long fur skirt.

She boosted her height in a pair of black pointy heels with a silver bow detail to match her necklace.

Keira and co-star Carrie Coon dressed to the brim on Tuesday for a screening of their film The Boston Strangler at New York’s Museum of Modern Art.

The Pirates Of The Caribbean alum performed as a goth while posing for shutter bugs while The Gilded Age actress, 42, exuded head-to-toe beige elegance.

Knightley stunned photographers when she arrived in a black balloon corset dress that accentuated her famously slim frame.

It was decorated with sequins that were shimmering under the red carpet lights.

The mother-of-two posed on black stilettos and sparkly bull’s blood nail polish.

The new version is written and directed by Matt Ruskin, while it also stars David Dastmalchian (The Suicide Squad, Dune), Chris Cooper, and Alessandro Nivola.

In real life, reporter Loretta passed away in 2018 at the age of 90. After the scandal was exposed, she became an award-winning medical reporter and the second woman to serve as editor-in-chief of the Globe’s editorial pages.

Knightley recently said of the film: “This is a harrowing story of the brutality of the male psyche and how disturbing and awful it can be told through the eyes of two women.”

“It’s a tough story to tell, because there are so many different twists and turns.”

It comes after the actress said she put “a lot of pressure on herself” and felt “trapped” after filming The Pirates Of The Caribbean in the early years of her career.

Keira discussed navigating fame in a new interview with Harper’s Bazaar UK and will also be on the cover of the April issue.

Upon realizing how much pressure she put on herself in the early years of her career, Keira said: ‘I was very hard on myself. I was never good enough. I was completely single-minded. I was very ambitious. I was so driven. I was always trying to get better and better, which is a stressful way to live your life.

I’m in awe of my 22-year-old self, because I wish I could have more of her back. And it was only by not being like this anymore that I realized how unusual it was. There was not an iota of me that you wouldn’t find a way around.

The London native is best known for playing a tomboy soccer player in the 2002 movie Bend It Like Beckham.

Boston Strangler is due out Friday, March 17th on Hulu.
